Описание

The purified proteolytic substance derived from the latex of Ficus spp. which include a variety of tropical fig trees. The material presents as white to off-white powders which are completely soluble in water (liquid fig latex concentrates are light brown to dark brown). The major active principle is ficin, IUB No. 3.4.22.3, CAS No. 9001-33-6.
Ficin has been cleared by the Meat and Poultry Inspection Division to soften tissues of beef cuts and of raw poultry muscle tissue of the hen, cock, mature turkey, mature duck, mature goose and mature guinea, as follows: Solutions consisting of water and approved proteolytic enzyme applied or injected into raw poultry tissues or cuts of beef shall not result in a weight gain of more than 3%. When approved proteolytic enzymes are used in mature poultry muscle tissue or on steaks or other raw meat cuts, there must be a label indicating such.
